LINT FLUE.

Application filed March 28, 1927. Serial No. 178,923.

This invention relates to lint feed fines for conducting lint fromlinters, and an object of the invention is to provide such a flue withmeans for discharging the heavier 5 foreign substances therefrom whilethe lint passes on through the flue.

Another object of the invention is to pro vide a lint feed flue forconducting lint from a linter, comprising an inclined strr ight, or

1 approximately straight, receiving portion having a discharge slotacross its lower portion through which the relatively heavy foreignsubstances that become detached and separated from the lint may pass tothe out side leaving the relatively clean lint free to pass on throughthe flue. This receiving portion of the flue is tapered andapproximately rectangular in cross section, thus preventing whirlingmovements of the air ands the lint being drawn through the fine, withthe result that the lint is prevented from being compacted into masses.

()ther objects will appear from the following description, referencebeing made to the drawing in which Fig. 1 is a side edge elevation, withparts in section, of our improved flue.

Fig. 2 is a side elevation showing a pair of lines in a relationship inwhich they are preferably assembled in connection with a linter.

Fig. 3 is a sectional view showing the means by which the parts at thelower end of the fluesare held in spaced relationship to provide adischarge slot for the heavier particles.

From the linter a metallic wall 1 inclines upwardly and outwardly andhas its upper edge extending into the lower end of the inclined fluereceiving portion 2 overlapping the lower wall 8 of said receivingpoi--- tion of the flue.

The wall 1 is spaced from the wall 3 of the receiving portion of theline providing a discharge slot or chute 4. The walls 1 and 3 are heldin this spaced relationship by interposed clips 5, preferaby locatednear the side walls of the flue so as to reduce as far as possible theobstruction formed thereby,

leaving a free discharge outlet for the heavier separated materials.

It will be noted that the receiving portion of the flue extends in anearly straight inclined direction and is approximately rectangular incross section, although it tapers upwardly to connection with the lineproper 6.

By use of this invention the heavier foreign substances are permitted toseparate from the relatively lighter lint fibers and drop out of theapparatus, while the lint fibers pass on through the flue, beingprevented from matting and felting by the straight inclined fluestructure. This straight inclined flue structure also permits theseparation of the foreign matter as described.

The construction may be varied within equivalent limits withoutdeparture from the nature and principle of the invention. We do notrestrict ourselves unnecessarily, but what we claim and desire to secureby Letters Patent is 1. A lint feed flue receiving portion approximatelyrectangular in cross section and composed of approximately straightinclined walls forming an upwardly tapering flue passage, and having adischarge opening for heavy particles near its end of greatest width.

2. An inclined lint feed flue having its lower end wider than its upperend and constituting a receiving end attached to a linter and providedwith a discharge slot adjacent to the linter through which heavierparticles may pass, while the lint continues to pass through the flue.

8. A lint feed flue having its receiving end attached to alinter andprovided with a discharge slot adjacent to the linter through whichheavier particles may pass, while the lint continues to pass through thetiue,said flue being approximately rectangular in cross section andcomposed of approximately straight inclined walls forming an upwardlytapered passage.

4. The combination with an upwardly inclined wall of a linter, of aninclined lint feed flue having its lower end enclosing said well andforming therewith a downwardly inclined opening.

5. The combination with a, linter having an upwardly inclined wall, ofan upwardly inclined lint; feed flue receiving portion approximatelyrectangular in cross section and comprising approximately st'ziightinclined Walls forming an upwardly tapering passage enclosing the outeredge of said first named In Wall and forming therewith a, dischargeopening below said first named Wall.
